Abstract: The removal of basic nitrogen compounds from the coker diesel by extraction with acidic ionic liquid as main denitrogenation agent were investigated. The experimental results show that good denitrogenation efficiency (up to 92%) for coker diesel can be obtained under the following conditions: the mass ratio of oil to denitrogenation agent 25, temperature of 25 ℃, stirring for 20 min under reflux and settling time of 1.5 h. Denitrogenation agent can be reused and there is no obvious decrease in the nitrogen removal efficiency (90%) after recycling 5 times.

摘要:  利用酸性离子液体作为脱氮剂脱除焦化柴油中碱性氮化物。结果表明,在m(原料油)/m(脱氮剂)为25,反应温度25℃,回流搅拌20min,沉降时间为1.5h条件下,焦化柴油的脱氮率可以达到92%以上。脱氮剂经过再生重复使用5次后其脱氮率仍可以达到90%。
